[ANN] luaposix 33.3.0 released

["Gary V. Vaughan" <gary@...>]

A library binding various POSIX APIs, including curses. POSIX is the IEEE
Portable Operating System Interface standard. luaposix is based on lposix
and lcurses.

I am happy to announce release 33.3.0 of luaposix.

luaposix's home page is at http://github.com/luaposix/luaposix/

## Noteworthy changes in release 33.3.0 (2015-02-28) [stable]

### New Features

  - Improved documentation of `sockaddr` tables for `posix.sys.socket` calls.

  - New `posix.sys.socket.getsockname` binding.

  - Remove the `posix.bit32` library, and use Lua’s built-in `bit32` library.

  - Can now be linked against NetBSD curses, albeit with several functions
    not implemented by that library returning a "not implemented" error as
    a consequence.

  - New functions `popen`, `popen_pipeline` and `pclose` mimic the POSIX
    functions of the same name while allowing tasks to be Lua functions.

  - `fdopen` has been re-added, working on all supported Lua versions.

  - `execx` allows a Lua function or command to be exec’d; `spawn` is now
    implemented in terms of it.

### Incompatible Changes

  - The ncurses-only `KEY_MOUSE` definition has been removed from
    `posix.curses`.

### Bugs Fixed

  - `posix.sys.resource` only provides RLIM_SAVED_CUR and RLIM_SAVED_MAX if
    they are defined by the C library (which FreeBSD 10 does not).

  - `posix.dirent.dir` and `posix.dirent.files` now raise a Lua `error()`
    when unable to open the path argument, for orthogonality with `io.lines`.

  - Workaround for manifest key clash between `posix.so` and `posix.lua` in
    LuaRocks.
